摘要 本设计完成了一座办公楼的建筑设计和部分结构设计。建筑高度26.70m(从地面标高到屋顶最高点的高度)。 本工程地震设计烈度为7度，抗震等级为四级。建筑防火等级为二级，建筑耐久年限为50年。在进行结构设计之前建筑设计已完成并由指导老师认可。 结构设计部分：主体采用框架结构，要求在建筑设计基础上布置结构，基础结构形式采用柱下独立基础。计算了水平(地震、风)方向和竖向荷载；人工计算一榀框架在水平荷载作用下和竖向荷载作用下的内力及水平侧移；人工计算了一榀框架的荷载效应组合及截面设计。 关键字 办公楼；设计；框架；荷载 Design of Guilin integrated business office building Student:Ling Wen Wu Teacher: Wang Qiang Abstract：This design has completed a integrated business office building’s architectural design and part of structural design. The height of the building is 26.7m (from the ground to the main structure cornice). This project’s seismic fortification intensity is 7degree; seismic fortification grade is grade four. The fire prevention grade of this building is grade two, the design working life of the building is 50 years. The architectural design have been completed and admitted by the academic advisor before the structural design. Structural design section: The major part of the subject adopts framework, demanding that the base of the architecture design should arrange construction, and the foundation scheme select strip foundation. Calculated the horizonal loads (seismic,wind) and vertical loads, and the stress under the function of these loads; calculated the excursion under the function of the horizoned loads and vertical loads; calculated the load effect combination and the cross-section design of the frame. Key words: office building; design; frame;load  目 次 摘 要 ………………………………………………………………Ⅰ Abstract ……………………………………………………………Ⅰ 结构计算书明……………………………………………… 2 结构计算书 …………………………………………………3 1 楼盖结构计算…………………………………………………3 2 连续梁计算 …………………………………………………11 3 框架结构计算 ………………………………………………19 4 基础结构计算 ………………………………………………65 5 楼梯计算 ……………………………………………………72 致谢…………………………………………………………………75 参考文献 …………………………………………………………76 结构计算书总说明 工程概况：本次设计工程为一综合办公楼，建筑主体结构共有6层，总高26.7m，每层层高均为3.9m；突出屋面的塔楼为楼梯间。建筑面积3923.9m2，占地面积756.5m2。 自然地表下1m内为填土，填土下3m厚为硬塑性粘土，再下为砾石层。粘土允许承载力为180kN/m2，砾石层允许承载力为300kN/m2。地下水位在地表以下2m，水质对混凝土无侵蚀。地震设计烈度7度，建筑场地类别为Ⅱ类，场地特征周期为0.35s，地面粗
